| titleOfInvention | Prepolymer composition, process for its production, and its use |
| abstract | Disclosed is a prepolymer composition which comprises 10 to 95% by weight of a first isocyanate-group-containing prepolymer (A) obtained by reacting an excess equivalent of an aromatic diisocyanate (c) containing an isocyanate group directly bonded to the aromatic nucleus with an oxyethylene-group-containing polyoxyalkylene polyol (a) of a relatively high molecular weight; 90 to 5% by weight of a second isocyanate-group-containing prepolymer (B) obtained by reacting an excess equivalent of an organic diisocyanate (d) not containing an isocyanate group directly bonded to the aromatic nucleus with an oxyethylene-group-containing polyoxyalkylene polyol (b) of a relatively high molecular weight; and, as the case may be, an unreacted substance of diisocyanate which has been used in the production of the respective prepolymers (A) and (B), the prepolymer composition containing the isocyanate group in a range of from 3 to 15% by weight, wherein the polyoxyalkylene polyol (a) and the polyoxyalkylene polyol (b) are either same or different each other, each consisting of at least one polyoxyalkylene polyol, and wherein the polyoxyalkylene polyol (a) and the polyoxyalkylene polyol (b) in total contain functional groups in an average number of above 2 but below 3 and have an average hydroxyl value of from 30 to 80 and an average content of the oxyethylene group of from 70 to 95% by weight; n a method for producing the prepolymer composition, which comprises forming a prepolymer (A) by reacting the polyoxyalkylene polyol (a) with the aromatic diisocyanate (c) in the presence of a prepolymer (B) or a prepolymer (B) containing unreacted substance of the organic diisocyanate (d); na reactively curable composition suitable for forming a substantially poreless coating layer or film of a hydrophilic polyurethane type resin, which consists of a combination of the above-mentioned prepolymer composition and a curing agent containing therein the isocyanate group and 2 or more reactive functional groups; and na moisture-permeable material, which comprises a laminated body of a substantially poreless coating layer or film of hydrophilic polyurethane type resin obtained by reactively curing a mixture of the above-mentioned prepolymer composition and a curing agent containing an isocyanate group and 2 or more reactive functional groups; and a porous substrate. |
